Hey guys, Exposing signal handlers from managed code is always the wrong solution.
If we're crashing in the runtime, a managed code signal handler has very little chance of works. It's a scenario we will never even consider supporting. I guess the simple solution is to add an embedding API call that queues signal handlers to be called first before chaining to the OS one. -- Rodrigo Sent from Nylas N1<https://link.nylas.com/link/d48tmovljcet4a9zmfuetdrqy/local-32fb72b2-e621/0?redirect=https%3A%2F%2Fnylas.com%2Fn1%3Fref%3Dn1>, the extensible, open source mail client.

I think this could work. Another advantage is that it would not require any code changes in the products, only Mono. I can have a look at implementing (and testing) this, unless the runtime team wants to do it?
